The awful shooting in a small Connecticut town has raised disturbing questions, but has also placed a spotlight on America's thriving gun business.

Taking a look at Black Friday just last month, U.S. shoppers weren't just buying toys and electronics, they were also buying a record number of guns.

On that single day, Nov. 23, the FBI did computerized background checks on more than 154,000 purchases of firearms. If you examine the month of November as a whole, Americans tried to buy 2 million guns.

There are more gun dealers and gun stores than there are major supermarkets.
